There is no 3rd Spartan project. There was the first one, that John and all the Spartans we know and love are a part of, and then there was the Spartan II project that Mendez was going to go oversee after he left the orginal Spartans. But we have never heard wind of them anymore. They only mention of it ( of it could just be a mistake ) was the Convo between Cortana and the other HUman AI in the Conversations of the Universe booklet.
As for Kelly and the Doctor, no one knows. Because the books pull from the Game, not the other way around.
